St Anthony Sand Dunes Idaho Information

The St. Anthony Sand Dunes are comprised of over 10,000 acres of quartz sand in the Snake River Plain. The dunes can range from 10ft tall to up to 400 ft tall. They are a popular destination in the summer for sand dune motor sports enthusiasts and are a critical winter range for elk, deer, and grouse. The big dunes are on the west side and include more technical steep riding opportunities including Choke Cherry, Devil's Dunes, and Dead Horse Bowl. The smaller dunes are located on the east side of the dunes and can be accessed most easily from the Red Road Area Access. Egin Lakes area is a good central location for accessing both the smaller dunes and the big dunes and is the closest access point to Thunder Mountain a.k.a. Crapo's Hill. Sand Hills resort is located at the east side of the sand dunes which are accessible year round (there can be considerable snow in the winter though). The Big dunes are closed in the winter west of Thunder mountain and Egin Lakes for winter habitat.
